Abstract: A method for processing information through a clearinghouse wherein a rewards provider (2402) assembles the reward program information and forwards it to a store chain central office (2404) for implementation. The store chain central office (2404) then transmits information to one or more of its stores (2406). The store (2406) provides a reward to a customer (2408) based upon the purchase of discount triggering items. Upon meeting the requirements for redeeming a reward, the customer (2408) redeems the reward at a gas station (2410) for gasoline. Redemption information received by the central office (2404) in the form of electronic files and redemption slips is then sent to a clearinghouse (2412) for processing. The clearinghouse (2412), receiving the information on a daily basis as bundled sums, processes the redemption information by invoicing respective manufacturers (2416) for products sold, and making payment to the stores (2406) for the costs of the discount triggering items which were sold.
